Collection device

Abstract

A collection device for a tissue removal device has a flow connection on the shaver side, which can be fluidically connected to a tissue discharge of the tissue removal device, a flow connection on the vacuum side, which can be fluidically connected to a vacuum device, a connection path which can be formed between the flow connection on the shaver side and the flow connection on the vacuum side and via which a fluid flow can be formed from the flow connection on the shaver side to the flow connection on the vacuum side, and a collection container which can be attached in the connection path for receiving tissue material from the fluid flow. A bypass path separate from the collection container can be formed between the flow connection on the shaver side and the flow connection on the vacuum side. The flow connection on the shaver side and the flow connection on the vacuum side are provided on a connection housing on which the collection container is held in a removable manner.

         6 . The collection device according to  claim 1 , wherein the collection container forms a flow portion of the connection path between an inlet opening and an outlet opening, wherein a collection receptacle delimited by a sieve device is provided in the flow portion. 
     
     
         7 . The collection device according to  claim 6 , wherein the sieve device is formed by a planar sieve surface, which is attached upstream of the outlet opening in the direction of flow. 
     
     
         8 . The collection device according to  claim 6 , wherein the collection receptacle can be observed through a transparent region of the collection container. 
     
     
         9 . The collection device according to  claim 6 , wherein a closing element is held on the removable collection container and can be adjusted between a first open position in which the inlet opening of the collection receptacle is released, and a closed position, in which the inlet opening is closed. 
     
     
         10 . The collection device according to  claim 9 , wherein the closing element can be brought automatically into the first open position when the collection container is attached to the connection housing. 
     
     
         11 . The collection device according to  claim 9 , wherein the closing element can be brought into the closed position automatically when it is removed from the collection container. 
     
     
         12 . The collection device according to  claim 9 , wherein the closing element has an actuating element via which the closing element is adjustable into the first open position when the collection container is attached, by interacting with the connection housing. 
     
     
         13 . The collection device according to  claim 9 , wherein the closing element is biased into the closed position. 
     
     
         14 . The collection device according to  claim 6 , wherein the collection receptacle can be emptied by means of a piston. 
     
     
         15 . The collection device according to  claim 14 , wherein the collection container has a container opening which can be closed by the closing element and which is released in a second open position of the closing element, and the piston is held on one side of the collection receptacle facing away from the closing element and can be displaced along the collection receptacle in the direction of the container opening. 
     
     
         16 . The collection device according to  claim 14 , wherein the piston is displaceable along an inner surface of the sieve device. 
     
     
         17 . The collection device according to  claim 3 , wherein the switching device can be switched via a rotary member.
